Effect of E-cigarette Use and Social Network on Smoking Behavior Change: An agent-based model of E-cigarette and Cigarette Interaction [PDF]

arXiv, 2019
Despite a general reduction in smoking in many areas of the developed world, it remains one of the biggest public health threats. As an alternative to tobacco, the use of electronic cigarettes (ECig) has been increased dramatically over the last decade. ECig use is hypothesized to impact smoking behavior through several pathways, not only as a means of

Endogenous cholinergic inputs and local circuit mechanisms govern the phasic mesolimbic dopamine response to nicotine [PDF]

, 2013
Nicotine exerts its reinforcing action by stimulating nicotinic acetylcholine receptors (nAChRs) and boosting dopamine (DA) output from the ventral tegmental area (VTA).

KYNA Ameliorates Hepatic Ischemia–Reperfusion Injury by Activating the Hippo Signalling Pathway via FTO‐Dependent m6A Demethylation of LATS1

Cell Proliferation, EarlyView.
Our study elucidates the cellular and molecular mechanisms underlying KYNA's protective effects against HIRI. It emphasises that KYNA modulates the methylation status of the Hippo signalling pathway through the activation of AHR, thereby mitigating damage by promoting LATS1 degradation and facilitating the nuclear translocation of YAP. ABSTRACT Hepatic

A physical model of nicotinic ACh receptor kinetics [PDF]

arXiv, 2008
We present a new approach to nicotinic receptor kinetics and a new model explaining random variabilities in the duration of open events. The model gives new interpretation on brief and long receptor openings and predicts (for two identical binding sites) the presence of three components in the open time distribution: two brief and a long.

Mutations affecting agonist sensitivity of the nicotinic acetylcholine receptor

Biophysical Journal, 1991
The nicotinic acetylcholine receptor (AChR) is a pentameric transmembrane protein (alpha 2 beta gamma delta) that binds the neurotransmitter acetylcholine (ACh) and transduces this binding into the opening of a cation selective channel. The agonist, competitive antagonist, and snake toxin binding functions of the AChR are associated with the alpha ...

Macrophages and autophagy: partners in crime

The FEBS Journal, EarlyView.
Autophagy is a key regulator of macrophage function, influencing critical processes like polarization, cytokine secretion, and phagocytosis. Its impact on macrophage behavior varies across different tissues and disease contexts, where it can either promote protective responses or contribute to detrimental outcomes, depending on the physiological or ...

Acetylcholine receptor based chemogenetics engineered for neuronal inhibition and seizure control assessed in mice

Nature Communications
Epilepsy is a prevalent disorder involving neuronal network hyperexcitability, yet existing therapeutic strategies often fail to provide optimal patient outcomes. Chemogenetic approaches, where exogenous receptors are expressed in defined brain areas and

Nicotinic agonist modulation of neurotransmitter levels in the rat frontoparietal cortex.

Japanese Journal of Pharmacology, 1997
Anabaseine is a naturally occurring toxin that stimulates a variety of neuronal and muscle nicotinic receptors. GTS-21 [3-(2,4-dimethoxybenzylidene)anabaseine], an anabaseine derivative, selectively stimulates alpha 7-containing nicotinic receptors. Here

An adamantane‐based ligand as a novel chemical tool for thermosensory TRPM8 channel therapeutic modulation

The FEBS Journal, EarlyView.
Transient receptor potential cation channel subfamily M member 8 (TRPM8) is a cationic thermosensory channel crucial for cold sensation and menthol response. TRPM8 dysfunction leads to sensory symptoms such as cold allodynia. Targeting TRPM8 is important for treating diseases like peripheral neuropathies and cancer.
